The matrix of a liquid can contain compounds that cannot be not measured by XRF (e.g. -CH2-, -CHOOCH2- or -CH2OCH2-). The matrix effects of these compounds, however, are very different and influence the accuracy. For an accurate analysis of elements like sulfur the determination of these compounds is crucial. These compounds have a high influence on the Compton scattered tube intensity. For this reason the FP model is extended with a model to calculate the theoretical intensity of scattered tube intensity. Oil-Trace exploits this advanced FP model to correct for the influence of these compounds, resulting in increased accuracy for elements like Mg, Al, Si, S and P.


Accurate net intensities are the basis of good-quality trace element analyses. Furthermore accurate matrix correction is vital, especially in cases where not all major element data are available. Pro-Trace offers specific features for calculating net intensities in trace element analysis and accurate matrix correction when the total matrix is unknown. Accessed via a periodic table the smart element selector is an easy-to-use feature, which ensures that the user measures the correct combination of elements for a series of element subsets. The channels, instrument parameters and background offsets, are input to the analytical program.
Pro-Trace makes use of shared background positions to reduce measurement times.

Non-ambient components/Applications

The MHC-trans is a dedicated chamber for in situ X-ray diffraction with controlled temperature and humidity conditions. It is ideal for in situ studies of dynamic crystal structure changes, phase transformation, chemical reactions and so on in organic and inorganic polycrystalline materials. Thanks to the chamber design not only dry powders but also liquid dispersions/suspensions can be studied. The transmission geometry of MHC-trans enables basic SAXS measurements.
